To all whom it may concern:

Be it known that I, BENJAMIN- WHITFIELD Mon'roN, a citizen of the'UnitedStates-and a resident of Williston, in the-county of Levy and Statecit-Florida, have invented certain facilitate the breaking or plowing"thereof asdalso serve to sever obstructions which may impede theprogress of breaking or plowing the earth.

It is-a further object-0f the inventionthat thecutteror colterattachment may be easily securedto the wheels of a tractor and-at a lowcost.

- It is a still further object of the'inventio-n that the cutterattachment be durable and reliable inoperation.

Other objects and advantages relating to trating themannerin which thecutter sec tions are secured in position.-

Similar reference numerals throughout the drawings refer to similarparts.

I It may be' here mentioned that the present invention is shown whenassociated withthe- Serial No. 591,381,

so-called Fo-rdson type of tractor for B there is indicateda push barand at DIa disk plow which isadaptedgto beoperatedfl;

through said push bar B; This plow oper- 1 ates attherear of the'frontwheehW '1. In a tractor of the type shown in Figure 1,

the rim-of a front wheel W comprises-two sections'l o and 16. Thesesections are each f formed at their opposing edges with .afiange 17,Figure 3. From the hub 18 of each wheel there extends two sets ofspokes, name'- ly 19 and 20; the spokes19 occurring. alternately anddiverging. from" the spokes 20 as" illustratedin Figure 1. The upperends of: these spokes are positioned: between the flanges 17 of the rimsections 15 and-16 and, secured by rivets 17, the rivets extendingthrough the spokes andflanges ByFthis.

ness of the wheel spokes} In carryingout thepresent invention rela l.tive tothe colter or cutter, I provide aplu.-' ralityofsectionsS,,Figure 2. Each section beingin the form of a plate arcuate in shape.and having its outer periphery bevelled to iorm a cutting edge ,as at-22. Each sectionj 15 also formed upon itsfinner edge-with a re-Y',

I construction the flanges are spaced the thick-1 cess 23 which is ofthe same width, as ,either l,

is provided which is one-halfthewidthiof being broughttogetherto form'acomplete circle, the adjacent oii'sets-QA of thepair of;

sections will'forma recess adapted to receive;

either oft'he spokes 19 or 20ofthe wheel W"; Eachv section S is ofsubstantiallythe same] thickness as the two spokes 19 and 20.. Alsoeachsection S is. provided-with a plurality of openings 25 adapted toreceive acotterpin, p

26 or like securing means.

In assembling or positioning a cutter upon a front wheel W', thesections S are posi-yj tioned? so that the inner peripheries thereof arebetween the flanges 17 of the wheel sections 15 and-1 16:- Therecesses23 of the 's ections S will receive the outer ends of alternatewheel spokes while the recesses formed the olisets 2-1 of the sections Swill receive 7 the remainder of wheel spokes. By this construction thecutter sections are seated upon the outer ends of the wheel spokes. Thecutter sections, as shown in Figure l, are five in number, although thisis merely arbitrary and any number of sections may be used. The cotterpins 26 are positioned in the openings 25 to hold the cutter sectionsinposition.

The cutter sections are shown as applied to the front wheels of thetractor in that the construction of these wheels offer an easyapplication of the same, and also it is believed that cutters upon thesewheels produce the best operative results. I

In the operation of the present invention, as the tractor proceeds thedisk D is pushed forward and by using the cutters upon the front wheelsany obstructions such as roots,

or the like, which may be in the earth are cut and thus not impeding theoperation of the disk plow D. Also it shouldbe here mentioned that bycutting the earth previous to plowing the same the breaking of theearth'by the disk plow is greatly facilitated.

It is also important'to be here noted that in the use of a tractor forplowing equipped with cutters of the present invention, that thesteering of the tractor is made much easier.' This is especially truewhen the tractor is used for breaking loose soil.

While I have shown my invention associated with a particular tractor andalso with a particular type of plow, I wish it to be understood that Iam aware of the fact changes may be made in the construction andapplication of the cutter sections withthat numerous advantages of thesame may be obtained by employment with other types of tractors and withother types of plows; also that I am aware of the fact that slight outdeparting from the spirit of my invention as indicated by the appendedclaims.
